Activating Your Glutes Could Be the Secret to a Bigger Butt — Here's How to Do It

Donkey Kicks

Start on all fours, with your hands directly under your shoulders and your knees directly under your hips.

Keep your right knee at a 90-degree angle as you slowly raise your leg behind you until your thigh is almost parallel to the floor. Pulse your flexed foot toward the ceiling by squeezing your glutes. Your back should remain perfectly still in a neutral spine. The motion should be small and controlled with your muscle doing the work, not momentum.
